I was trying to convert all of my emails from OST to PST format three months ago. I tried a lot of manual ways to get reliable results, but couldn't get reliable results. Then one of my colleagues recommended using the OST to PST Converter. This is a powerful file conversion utility. All new Windows versions are supported by the OST to PST converter. This software also works with Windows XP and Vista. This is a tool that you can use.
